简要总结
identification of optimal duration for hamstring muscle stretch by using 3 different time of stretch 15,30,60 seconds .100 subjects will be participated in this study divided into 4 group one control and 3 experimental groups according to stretch time.
详细描述
Abstract:
OBJECTIVE
To explore the effect of variable stretching intervals on neural function and ROM.
DESIGN: Randomized controlled trial Participants: In this trial, 100 participants will participate in the study diagnosed with tight hamstring muscles (defined as the inability to extend the knee to less than 20° of knee flexion) were randomly assigned to the control group or one of the 3 intervention groups Interventions: The three experimental groups will stretched 5 times per week for 4 weeks for 15, 30, and 60 seconds, respectively the control group did not stretch Main Outcome Measures: The neurophysiological outcome measures included peak to peak somatosensory evoked potential for dermatomes L3,L4,L5, and S1. Secondary outcome measures included knee ROM. All outcome measures will be assessed immediately after the treatment session and 24 hours after the treatment session.

入选标准
- •Subjects had to demonstrate "tight" hamstring muscles, defined as inability to extend the knee to less than 20 degrees of knee flexion with the femur held at 90 degrees of hip flexion while the person was positioned supine. Subjects were also screened to rule out knee joint flexion contractures by checking knee extension ROM, while they were lying in a prone position
排除标准
- •Using of medical aids, and suffering from any neurological or cognitive impairment, limiting cardio-respiratory conditions, or had undergone recent surgery (within the past 12 months). Having any hip or knee replacements or any history of pathology in the low back, hips, or knees for the 3 months prior to the study
研究组 & 干预措施
15 second stretch
Stretching of the hamstring muscles was performed by the primary researcher for 15 seconds. A straight-leg-raising technique was used for this stretch because we believe that it is commonly used in the clinical setting for elderly people. All subjects were supine lying as flat as possible
干预措施: stretch hamstring (Procedure)
30 second stretch
Stretching of the hamstring muscles was performed by the primary researcher for 30 seconds. A straight-leg-raising technique was used for this stretch because we believe that it is commonly used in the clinical setting for elderly people. All subjects were supine lying as flat as possible
干预措施: stretch hamstring (Procedure)
60 second stretch
Stretching of the hamstring muscles was performed by the primary researcher for 60 seconds. A straight-leg-raising technique was used for this stretch because we believe that it is commonly used in the clinical setting for elderly people. All subjects were supine lying as flat as possible
干预措施: stretch hamstring (Procedure)
control
The control group followed the same procedures except that no stretching force was applied at the end
干预措施: stretch hamstring (Procedure)
结局指标
主要结局
Neurophysiological findings.
时间窗: Assessments of the change of DSSEPs from baseline to immediatly after session and at 24 hour after session
Neurophysiological findings included peak to peak somatosensory evoked potentials (DSSEPs) for L3,L4,L5,S1 dermatomes.
次要结局
- ROM(Assessments of the change of Knee ROM from baseline to immediatly after session and at 24 hour after session)
